number of days between dates

[JT]

I need to calculate the number of days between dates but
am not having much luck with the datediff function.
Here's the code I'm trying to use:

Dim vNumberofDays As Integer
Dim vDate1 As Date
Dim vDate2 As Date

Range("A1").Select
ActiveCell.Offset(1, 25).Select

Do Until IsEmpty(ActiveCell.Offset(0, -3)) = True
vDate1 = ActiveCell.Offset(0, -16)
vDate2 = ActiveCell.Offset(0, -9)
vNumberofDays = DateDiff(d, vDate1, vDate2)
ActiveCell = vNumberofDays
vNumberofDays = 0
ActiveCell.Offset(1, 0).Select
Loop

Any help would be appreciated.....Thanks

You can just subtract the earlier date from the later date to get
the number of days. E.g.,
vNumberOfDays = vDate2-vDate1

vNumberofDays = DateDiff(d, vDate1, vDate2)

The first argument needs to be in quotes, i.e. "d".

As Chip mentioned, to get a difference in days, you can just subtract, but the
problem with your code is that the first argument to DateDiff must be a
string.

You used the *variable* named d. This would be interpreted by VBA as a variant
variable, and since you didn't set its value, it is an empty string. You
should probably be writing something like

vNumberofDays = DateDiff("d", vDate1, vDate2)

You can eliminate these sorts of errors if you include the line

Option Explicit

at the top of the module. If you do this, the code will not compile; you'll
get an error that d has not been dim'd.
